Avaliação da qualidade da água purificada em farmácias magistrais da região de São José do Rio Preto, SP

Water is the raw material used most in the production of diverse pharmaceutical forms and, being a constituent of the formulation itself, is subject to a number of physico-chemical and microbiological specifications. In addition, it is indispensable for laboratory tests and the cleaning of equipment and apparatus. The aim of this study was to ascertain the degree of physicochemical and microbiological contamination of purified water used in compounding pharmacies in the city of São José do Rio Preto, SP, Brazil. Samples were taken as recommended in the USP Pharmacopeia, with careful aseptic technique, and sent immediately the to quality control laboratory. Physicochemical properties were analyzed, including appearance, pH, conductivity, residue after evaporation, ammonia, calcium, chloride, heavy metals, sulfate and oxidizable substances, and microbiological tests were performed: total aerobic microbial count and detection of total and thermotolerant coliforms and Pseudomonas aeruginosa. Results showed that some parameters did not conform to the standards, especially pH, conductivity, inorganic impurities, oxidizable substances and microbiological test data, in 10%, 17%, 10%, 14% and 20% of the analyzed samples, respectively, This points to the need for greater care in the production and/or storage of purified water in these pharmaceutical establishments.

Detecção de anticorpos anti-leishmania infantum syn chagasi em cães de São José do Rio Preto, São Paulo

Visceral leishmaniasis (VL) has been a widespread zoonosis in São Paulo since 1998, when the first autochthonous canine case was identified in Araçatuba. The aim of this study was to determine the occurrence of anti-Leishmania infantum syn chagasi antibodies in serum samples of 584 dogs from São José do Rio Preto, São Paulo, a non endemic area for the disease. Five dogs (0.86%) seroconverted by ELISA and one (0.17%) by immunochromatography. The indirect immunofluorescent reaction, carried out in 138 animals whose optical densities were above or close to ELISA's cutt-off point, evidenced two dogs (1.45%) with titers above 1:40. Only one dog was serum-reactive on the three techniques. Although there was not a history of displacing this animal to endemic areas, the dog had been acquired in a region with canine and human cases of VL. These results suggests that there were no autochthonous cases of canine VL in this population.

Diferenças sazonais no padrão endócrino e ovariano do ciclo estral de novilhas bos taurus indicus (Nelore)

Estrous cycle of eight Nelore heifers were evaluated during different seasons of the year (autumn n=11; winter n=8; spring n=9 and summer n=9) with daily count and measurement of follicles ≥3mm, blood was collected every 12h for LH and progesterone (P4), and after estrous every 3h for LH peak. Five ovariectomized heifers were injected with 17β-estradiol (2μg/kg) every season and blood samples collected every 3h (for 30h) thereafter for LH quantification. The monthly percent body weight difference (Δ%) did not vary among seasons. P4 concentration was higher (p<0.01) and follicle number lower during autumn and summer compared to winter and spring. During winter there were more estrous cycles with three and during summer only cycles with two follicular waves (p<0.01). As LH secretion did not vary despite P4 concentration and as there was negative correlation between higher P4 values and daily percentile variation of photoperiod (Δ%, p<0.01; r= -0.45) it is possible to suppose that there is seasonal variation on luteal cell sensitivity to LH. In the ovariectomized Nelore heifers, the LH basal concentration (without estradiol stimulus, p=0.02) and the LH response to estradiol (p<0.01) were lower during summer, leading to the hypothesis that there is seasonal variation of hypothalamic sensitivity to estradiol. According to the present experiment there are suggestions of seasonal reproduction in Nelore heifers.
